David (Hebrew: דָּוִד, דָּוִיד, Modern David Tiberian Dāwîḏ; ISO 259-3 Dawid; Strong's Daveed; beloved; Arabic: داوود‎ or داود‎ Dāwūd) was, according to the Hebrew Bible, the second king of the United Kingdom of Israel and, according to the Gospel of Matthew and the Gospel of Luke, an ancestor of Jesus. David is seen as a major Prophet in Islamic traditions. His life is conventionally dated to c. 1040–970 BC, his reign over Judah c. 1010–1003 BC,^{[citation needed]} and his reign over the United Kingdom of Israel c. 1003–970 BC.^{[citation needed]} The Books of Samuel, 1 Kings, and 1 Chronicles are the only sources of information on David, although the Tel Dan stele records "House of David", which some take as confirmation of the existence in the mid-9th century BC of a Judean royal dynasty called the "House of David".

David is very important to Jewish, Christian and Islamic doctrine and culture. In Judaism, David, or David HaMelekh, is the King of Israel, and the Jewish people. Jewish tradition maintains that a direct descendant of David will be the Messiah. In Islam, he is known as Dawud, considered to be a prophet and the king of a nation. He is depicted as a righteous king, though not without faults, as well as an acclaimed warrior, musician, and poet, traditionally credited for composing many of the psalms contained in the Book of Psalms.

David Reeves Boggs (born 1950) is an electrical and radio engineer from the United States who developed early prototypes of Internet protocols, file servers, gateways, network interface cards and, along with Robert Metcalfe and others, co-invented Ethernet, the most popular family of technologies for local area computer networks.

Boggs attended Woodrow Wilson High School (Washington, D.C.) and graduated in 1968. Boggs graduated from Princeton University. As a young graduate he worked at Xerox PARC, where he met Robert Metcalfe while the latter was debugging an Interface Message Processor interface for the PARC systems group. Since Boggs had considerable experience as an amateur radio operator, he recognized similarities between Metcalfe's theories and radio broadcasting technologies and joined his project. According to The Economist, "the two would co-invent Ethernet, with Mr Metcalfe generating the ideas and Mr Boggs figuring out how to build the system."

During 1973 they built several Ethernet interfaces for the Xerox Alto pioneering personal computer. On March 31, 1975, Xerox filed a patent application listing Metcalfe, Boggs, Chuck Thacker and Butler Lampson as inventors. In 1976, after 18 months in the writing, they published "Ethernet: Distributed Packet Switching for Local Computer Networks", Ethernet's seminal paper. It was reprinted in a special 25th anniversary issue of the Communications of the ACM. He produced a slide for a talk at the June 1976 National Computer Conference from a Metcalfe sketch of Ethernet terminology that was widely reproduced. The original prototype circuit is now in the National Museum of American History at the Smithsonian Institution.
